You're asking a two year old to interpret Kafka when you set the camera

Good points, Jos. And a clear explanation of what's going on with
fluorescent lights.

I mentioned a few days ago that I had some problems with the white balance on
the K20. If some
technically minded soul could possibly tell me WTF is happening with the white
balance in this
series of shot I would be most appreciative.
Six pictures shot within about two seconds of each other,
I don't know what's causing that, but I've seen a bit of it as well. It
happened to me in a room with mixed fluorescent and tungsten lighting. Only
once have I seen it change from one shot to the next. I expect it will go away
with the first firmware update.

I've seen shifts like that whenever I'm working in conditions where
there is flourescent lighting, with any camera. The cycling of
fourescent lights is what's to blame, in my opinion. They only hold a
particular color temperature for a fraction of a second, their color
temperature is only
I just put it down to the nature af AWB.
I've had similar situations with all my DSLR's.

Not that it will help you catch a moving dog, but... if you have
access to that room again and want to shoot a series of shots at
something closer to 1/30 second, you might find that the WB is a lot

I have experience similar, other than the second last one. I think its
the AWB and the type of lighting in the room.

Interesting. That's a very logical explananation. I suspect I've seen it a lot
more than i realize. I may just correct it in conversion without giving it much
thought. Because if this shift occurs with the kind of regularity others have
suggessted, I must have seen quite a bit of it in 30,000

It's the way the lights cycle.
I see it a lot.
With the faster shutter speed you are seeing the change between
different banks of lights - hence the apparent split lighting on each
frame.
It's one of the reasons I rarely shoot indoor dog events like agility.
I shoot a big obedience trial in May

If I understand the way the fluorescent lights work, that shouldn't
